2024 Hurricane Season Breaks an Unusual Record, Thanks to Hot Water

The 2024 hurricane season has already made history, setting an unprecedented record that highlights the stark contrast between Atlantic and Pacific storm activity. For the first time since satellite monitoring began in 1966, the Atlantic basin has generated more accumulated cyclone energy (ACE) than the entire Pacific Ocean through early July. This unusual phenomenon is largely attributed to the exceptionally warm water temperatures across much of the North Atlantic. Phil Klotzbach, a senior research scientist at Colorado State University, explains that these abnormally high ocean temperatures are influencing storm activity in both oceans, albeit in opposite ways. In the Atlantic, the warm waters have fueled an active start to the hurricane season. The region has already experienced several named storms, including the powerful Hurricane Beryl in early July. This early season activity has contributed to the record-breaking ACE levels, which measure the total energy of a hurricane season based on storm frequency and maximum wind speeds.

Conversely, the Pacific has seen an unusually quiet start to its tropical cyclone season. The western North Pacific experienced only one typhoon in May, and for only the second time on record since 1950, it went without a named storm from June 1 to July 15. In the eastern North Pacific, Tropical Storm Aletta's formation on July 4 marked the latest start to the season on record in that region. Scientists attribute this lack of Pacific storm activity to several factors, including the absence of a strong monsoon trough in the western North Pacific and excessive easterly wind shear in the eastern North Pacific. Interestingly, the warm Atlantic waters are contributing to these conditions by influencing global wind patterns. The dramatic spike in tropical Atlantic water temperatures from March to June 2024 has persisted, creating a La Niña-like circulation pattern. This pattern reduces westerly wind shear in the Atlantic, making conditions more favorable for storm formation. However, it increases easterly winds in the eastern North Pacific, hindering tropical storm development in that region. While it's still early in the hurricane season, forecasters predict above-normal activity for the Atlantic basin. The National Oceanic and Atmospheric Administration (NOAA) forecasts 17 to 25 named storms, including 8 to 13 hurricanes, of which 4 to 7 could become major hurricanes.

As the season progresses, researchers will continue to study the influence of climate change and other factors on tropical cyclone patterns. The unusual start to the 2024 season serves as a reminder of the complex interplay between oceanic and atmospheric conditions in shaping hurricane activity across different regions.

An open letter to the U.S. Congress

Let Biden’s LNG pause stand!

108 so far! Help us get to 250 signers!

I’m writing as a constituent and someone who’s deeply worried about the climate crisis to say that Congressional investigations into President Biden's pause on new Liquefied Natural Gas export permits are unnecessary and ill-informed. The facts are clear that this is a temporary pause on new LNG permits - it will not affect existing exports or new LNG export terminals that are already working or under construction. Second, only Department of Energy permits, and only those applying to LNG exports, will be covered by the pause. Our allies in Europe and beyond will not face shortages or disruptions in their fuel supplies as a result. Climate scientists and energy economists are clear: LNG is already bad for the climate, and is already diving up prices for US consumers, at a time when our allies in Europe are already reducing demand for fossil fuels. The LNG pause is a smart decision by President Biden, and Congress should focus its effort on making it permanent, and accelerating the transition to clean, renewable energy at home and abroad. Thanks.

Monitoring Climate Change and Its Impact: The Power of GIS 

GIS plays a vital role in monitoring climate change by transforming environmental data into visual insights, helping researchers, planners, and communities understand impacts, track changes, and make informed decisions.

 Why GIS Matters in Climate Monitoring

GIS transforms satellite and environmental data into visual, interactive maps—giving scientists, planners, and communities the tools to:

 Monitor Deforestation: Track forest loss and land use change using multi-temporal imagery.

 Observe Glacial Retreat & Sea-Level Rise: Detect shrinking ice caps, rising coastlines, and erosion hotspots.

 Map Urban Heat Islands: Analyze temperature patterns to plan greener, cooler cities.

These aren’t just data points—they're living maps that help us make smarter, faster decisions.

How It Works: A Simple Workflow

To create a carbon emissions map, start by gathering key data—such as pollutant levels and monitoring station locations. Import boundary layers and adjust their opacity for better visual clarity. Upload or enter your data, ensuring coordinates are accurately mapped. Use the Bubble tool to display the “Pollution average” across five data categories, setting a radius of 12 and choosing an appropriate color scheme. Customize the map’s layers and styles to improve readability. Once complete, analyze the map for meaningful insights and share it to help raise awareness and support informed environmental action.

Use Case: Mapping Methane Emissions from Permafrost Thaw

GIS is used to monitor and model methane release from thawing permafrost in Arctic regions. By integrating satellite imagery, soil temperature data, and terrain models, GIS helps researchers visualize methane hotspots, track emission trends, and predict future climate feedback loops—an uncommon but critical application in climate science.

Conclusion

GIS turns climate data into meaningful insights, helping us monitor environmental changes, design resilient infrastructure, and involve communities in climate solutions. Its ability to visualize and interpret change makes it an essential tool in tackling the climate crisis.

Open Tools Make It Easier

Climate Change Science

Climate Science: Understanding and Mitigating Global Change

Understanding and Mitigation of Climate Change Through Climate Science The challenges brought about by the phenomenon of climate change are quite challenging for the world. Despite numerous decades of effort in scientific research, there has always been something new close to the most fundamental causes, impacts, and potential remedies of this crisis. Climate change science tends to encompass some elements of science application for the public, including the winds, the ocean currents, and ecological and environmental impacts, in the study of how human actions and natural changes affect the functioning of and modify the natural properties of environments. This is what this article wants to look at, what it will call the key definitions of climate change science, its impacts, and the measures being taken to address the effects. What is Climate Change? Climate change on a global scale, however, would mean that significant, long-term changes in weather aspects leading to a rise in average global temperatures have occurred. All in all, however, it is observed that human activities, most notably the combustion of fossil fuels like coal, oil, and natural gas, have put an extra pot of gold for warming the atmosphere. Such activities have seen many greenhouse gases like carbon dioxide (CO₂), methane (CH₄), and nitrous oxide (N₂O) released into the atmosphere. These gases trap heat and stop it from escaping the earth's atmosphere, a process we term the greenhouse effect. The Art of Foresight Greenhouse Gas Emissions: The most important driver of today's global change is the increase of greenhouse gases in the air due to the action of human interventions. The combustion of fossil fuels for energy consumption releases carbon dioxide into the atmosphere. Besides, its sectors of agriculture, deforestation, and industrial activity contribute to the buildup of greenhouse gases. The more greenhouse gases that exist in the atmosphere, the more powerful the greenhouse effect consequently leading to global warming. - Global Warming: From the late 19th century, the average Earth temperature has risen by about 1.2°C (2.2°F) with the majority of this occurring from the late 1970s. The increased temperature changed the population distribution of the weather systems that pass through on Earth, contributing to forms of more extreme weather events such as high heat waves, heavy rains, and long-term droughts. - Ocean melt and ice: the warming up of our planet surely also affects the oceans and polar regions gravely. The rise in temperature causes the melting of ice, which feeds glaciers and ice sheets causing sea level rise. Melting ice together with the Earth's declining albedo (reflectivity) means that less sunlight gets reflected into space, which effectively exacerbates warming. Thus, the oceans absorb a great part of this energy and heat up as a result. Because of this, the engineered warming of the oceans leads to the disruption of marine ecosystems as well as the bleaching of coral reefs. - Feedback Loops: Climate science includes the recognition of many climate feedback loops amplifying warming as one good example through the melting ice surfaces increasing the absorption of the dark ocean layer or ground beneath it. This increased heat absorption leads to more melting of ice. Likewise, the thawing of permafrost releases stored methane powerful greenhouse gas into the atmosphere, causing more global heating. Impacts of Climate Change Climate change has impacts on a very wide range of issues including ecosystems, weather patterns, agriculture, human health, and economics. The following are the most important of these impacts: - Extreme Weather Events: Greater warmth in the world has caused increased frequencies of extreme heatwaves, storms, hurricanes, and wildfires. These disasters are usually associated with loss, displacement, and death as well as damage to properties. - Rising Sea Level: Moreover, as a result of ice melting and the thermal expansion of seawater, the world is now undergoing a rise in the average level of rivers and oceans. The worst-case scenario that is going to happen will be when sea level rise reaches coastal cities and small island nations displacing millions of people and endangering infrastructure. - Biodiversity Loss: Weather patterns and temperatures change, so habitats transform and pose challenges to the survival of the species. Animals and plants can't adapt quickly, leading to population losses and extinctions. - Agricultural Disruption: Climate changes interfere with the level of crop production due to changes in rainfall distribution, droughts, and temperature extreme events. Therefore threats to food security in particular at a regional level with people's livelihoods being based mainly on agriculture. - Human Health: Climate change aggravates health problems with, for instance, diseases induced by heat, respiratory difficulties, and the spreading of infectious diseases. The changes in the ecosystems also mean that there is less clean water and food for people to meet the needs of their daily lives. Mitigation of Climate Impact Climate change has serious consequences and must be mitigated, with the most crucial aspect being the mitigation of these impacts. Reducing emissions of GHGs and adaptation to climate change are very critical factors that will determine the saving of the world's future. - Greenhouse Gas Emission Cuts: The best way to minimize global warming is by reducing the amount of greenhouse gases emitted into the atmosphere. This could mean the installation of renewable energy, for instance, solar, wind, or hydropower in energy consumption, transport, and industry. On the other hand, governments and industries are increasingly considering lowering carbon products and deploying carbon capture and storage (CCS) technologies aimed at the most important part of the cause behind the CO2 collection in the atmosphere. - Forests and Land Use: Restoration and protection of forests, wetlands, and other natural habitats that can act as a carbon sink is essential. Right land management- introducing measures towards this matter like reforestation and agroforestry, carbon sequestration, and enhancing climate change adaptability can help. - INTERNATION COOPERATION AND POLICIES: International response, including the agreement of Paris, the US cutting emissions dramatically would activity to limit it well below 2 degrees Celsius-a limit. Keep, as a goal, the level at 1.5 degrees above the pre-industrial level. Therefore, emissions reduction by all means must be enforced by countries, and as they adapt to changes, they will also work together to support the poor countries in their climate efforts. Adaptation and Resilience: Mitigation, inevitable as it is, leaves adaptation out of the frame. Yet, effective coping mechanisms should be the fundamental priority of any effort at a national or local level taking pains to prepare for a climate-warming impact by establishing resilient infrastructure, enhancing disaster response systems, and protecting the vulnerable from bizarre meteorological phenomena. Investing in Climate Research: Research goes hand in hand with ongoing climate science to investigate and understand the whole cluster of phenomena brought about by changing the climate and offer new measures technology and adaptation. ipAddress is forever analyzing climate models and improving climate models upping their game to build better emitters as well as finding good ecosystem restoration methods.

Findings

Climate Change Science is a field of science evolving also to figure out the mechanisms behind global warming and impacts on the planet. The scientific community is diligently at work now studying patterns of changing climates and carving out new pathways to address effects. It is plain then that to address climate change a worldwide action is needed among nations and within states of those nations. Emissions can be reduced and the transition to renewable energy can be achieved. We can also preserve potentially crucial ecosystems and create investment support, such that we can be able to work toward a near future that is more sustainable and climate-resilient. It is what we do today that will, by far, have an impact on the world tomorrow. Read the full article

NVIDIA Earth-2 NIM Microservices Exposed For Faster Forecast

Faster Predictions: To Introduces NVIDIA Earth-2 NIM Microservices to Deliver Higher-Resolution Simulations 500x Faster. Weather technology firms can now create and implement AI models for snow, ice, and hail predictions with to new NVIDIA NIM microservices.

Two new NVIDIA NIM microservices that can 500x the speed of climate change modeling simulation results in NVIDIA Earth-2 were unveiled by NVIDIA today at SC24

NVIDIA Earth-2 NIM microservices

High-resolution, AI-enhanced, accelerated climate and weather models with interactive visualization.

Climate Digital Twin Cloud Platform

NVIDIA Earth-2 simulates and visualizes weather and climate predictions at a global scale with previously unheard-of speed and accuracy by combining the capabilities of artificial intelligence (AI), GPU acceleration, physical models, and computer graphics. The platform is made up of reference implementations and microservices for simulation, visualization, and artificial intelligence.

Users may employ AI-accelerated models to optimize and simulate real-world climate and weather outcomes with NVIDIA NIM microservices for Earth-2.

The Development Platform for Climate Science

GPU-Optimized and Accelerated Climate Simulation

To increase simulated days per day (SDPD), the Earth-2 development platform is tuned for GPU-accelerated numerical climate simulations at the km-scale.

Data Federation and Interactive Weather Visualization

Extremely large-scale, high-fidelity, interactive projections of global weather conditions are made possible by NVIDIA Omniverse. A data federation engine included into Omniverse Nucleus provides transparent data access across external databases and real-time feeds.

A digital twin platform called Earth-2 is used to model and visualize climate and weather phenomena. To help with forecasting extreme weather occurrences, the new NIM microservices give climate technology application developers cutting-edge generative AI-driven capabilities.

While maintaining data security, NVIDIA NIM microservices aid in the quick deployment of foundation models.

The frequency of extreme weather events is rising, which raises questions about readiness and safety for disasters as well as potential financial effects.

Nearly $62 billion in natural disaster insurance losses occurred in the first half of this year. Bloomberg estimates that is 70% greater than the 10-year average.

The CorrDiff NIM and FourCastNet NIM microservices are being made available by NVIDIA to assist weather technology firms in producing more accurate and high-resolution forecasts more rapidly. When compared to conventional systems, the NIM microservices also provide the highest energy efficiency.

New CorrDiff NIM Microservices for Higher-Resolution Modeling

Image Credit To NVIDIA

NVIDIA a generative AI model for super resolution at the kilometer scale is called CorrDiff. At GTC 2024, it demonstrated its potential to super-resolve typhoons over Taiwan. In order to produce weather patterns at a 12x better resolution, CorrDiff was trained using numerical simulations from the Weather Research and Forecasting (WRF) model.

Meteorologists and companies depend on high-resolution forecasts that can be shown within a few kilometers. In order to evaluate risk profiles, the insurance and reinsurance sectors depend on comprehensive meteorological data. However, it is frequently too expensive and time-consuming to be feasible to achieve this level of precision using conventional numerical weather forecast models like WRF or High-Resolution Rapid Refresh.

Compared to conventional high-resolution numerical weather prediction utilizing CPUs, the CorrDiff NIM microservice is 10,000 times more energy-efficient and 500 times quicker. Additionally, CorrDiff is currently functioning at a 300x greater scale. In addition to forecasting precipitation events, such as snow, ice, and hail, with visibility in kilometers, it is super-resolving, or enhancing the quality of lower-resolution photos or videos, for the whole United States.

Enabling Large Sets of Forecasts With New FourCastNet NIM Microservice

Image Credit To NVIDIA

High-resolution predictions are not necessary for all use cases. Larger forecast sets with coarser resolution are more advantageous for some applications. Due to computational limitations, state-of-the-art numerical models like as IFS and GFS can only provide 50 and 20 sets of predictions, respectively.

Global, medium-range coarse predictions are provided by the FourCastNet NIM microservice, which is now accessible. Providers may provide predictions over the following two weeks 5,000 times faster than with conventional numerical weather models by using the initial assimilated state from operational weather centers like the National Oceanic and Atmospheric Administration or the European Centre for Medium-Range Weather predictions.

By estimating hazards associated with extreme weather at a different scale, climate tech providers may now anticipate the chance of low-probability occurrences that are missed by present computational processes.

REU Weeks 9 & 10

*My official advice to do an REU if you are thinking about it!

I just realized I never made a post about my lasts two weeks at the REU. The specifics have definitely slipped my mind by now but I might be able to put together some bits and pieces of it.

We did our final presentations, and mine went very well. I am working on making another poster to present this research soon at a conference right now too!

Pretty sure in the last two weeks too is when I went on a solo hike in the area and there was a creepy man following me on the trail for nearly the whole time. We were talking for a while because I was being nice and he wasn't being super weird or anything but then he said something along the lines of, "these trails used to be so much nicer when you didn't have to worry about getting kidnapped on them". AND I WAS LIKE ???????? EXCUSE ME ????? Why would you say that???? I walked for only like a minute at max more and then turned around because it was also like 8:30 PM and getting dark out. I was so scared but I ended up being fine lol.

OVERALL:

Summer 2024 was honestly great. I didn't love my room mate or really any of the other students at the REU honestly which was upsetting, but I got to do so many new things. I got to go to two national parks I had never been to before, saw my first ever black squirrel in person, made new connections with professors, learned a lot about the area and culture, got to go to the moth man museum, DID SO MUCH THRIFTING AND ANTIQUING (where I was had the BEST goodwill I had ever gone to before and it made me so hype), and so so so much more. I made so many memories at my REU. It started off with being violently ill and someone sliding me some pepto bismol under the communal bathroom doors, to leaving with so many new memories of the area and many meaningful connections.

THIS IS YOUR ADVICE TO DO AN REU IF YOUR FIELD OFFERS ANY!!! If you are hesitant about applying please DM me and I am more than happy to talk about it with you! It is a really good research opportunity and so much more. I got to learn so much more about myself.
